SNARL-CATCHER FOR RING SPINNINGAND IWlSTlNG MACHINES.

SPECIFICATION forming part Of Letters Patent N 9. 687,981, datedDecember 3, 1901. Application filed June 3, 1901. $eria1No. 62,912. (Nomodel.)

T0 00% whom, it may concern:

Be it known that I, JOHN EASTWOOD, of Burnley, in the county ofLancaster, England, have invented certain new and useful Improvements inSnarl-Oatchers for Ring Spinning and Twisting Machines, of which thefollowing is a specification.

My invention relates to ring spinning and twisting machines, and isdesigned to catch or arrest snarls or broken ends when they occur duringthe working of the machine.

I so design my invention that it does not interfere with the operationof the machine, either during twisting or when the bobbins are beingdofied. 1

Reference is made to the accompanying drawings, in which- Figure 1 is aside view of the catcher and the screwed shank. Fig. 2 is an edge Viewof the same. Fig. 3 is a side-view of a portion of a spindle ring andrail and of the thread board or flap when in position during the pe riodof twisting, and Fig. 4: is a similar View during the period of doffing.

The reference-letters in all the drawings refer, respectively, to thesame parts.

In carrying my invention into efiect I form, by stamping or in otherconvenient method, out of iron, steel, brass, or other suitablematerial, a smalllblade A, hereinafter called the catcher. I form theupper part of A into a fork B, into which the fiat head 0 of a smallscrew D loosely fits. The back of the fork acts as a stop which preventsthe catcher A from swinging too near the spindle and also prevents itfrom oscillating while the frame is working. The catcher A is hinged tothe head 0 and is suspended on a small pin E, fixed in the fork-head Band passing loosely through the head 0. The shank D is screwed with athread similar to that of screws intended to be screwed into wood. Thecatcher A has formed in both its edges several downwardly-projectingnotches or serrations F.

In applying my invention I screw the shank D into the under side of thewooden threadboards G, which are hinged to the roller-beam H of themachine. I fix the catcher A in such a position that it will be clear ofthe thread when the latter is in its normal position, but sufficientlynear to arrest any snarl or broken end which may occur. When doffingtakes place and the thread-boards are turned up in the usual way, asshownin Fig. 4, the catcher A hangs vertically and is quite clear of thebobbin as the latter is being removed.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In combination with the thread-board of a ring-spinning machine, asupport D secured to said board, and a snarl-catcher consisting of ablade A with notches F formed in each edge and loosely hinged to thesupport D and free to oscillate in but one plane or direction.

2. The combination with the thread-board G, of the screw D securedthereto and having a fiat head 0, the notched or serrated blade A formedwith a fork at its upper end embracing the flat head O, and a pivotuniting the said head and fork, all constructed arranged and adapted tooperate substantially as set forth.

In testimony whereof I have aifixed my signature in presence of twowitnesses.

JOHN EASTWOOD.
